[0031] specific implementation

[0032] The present invention uses a distribution transformer load abnormal alarm method to solve the problem of low efficiency in processing massive, fuzzy and messy data in the prior art, and cannot well support related applications such as big data analysis and mining of distribution transformers, etc. question. Based on data such as power distribution transformer load information, basic information, and user power consumption information, the present invention uses technologies such as flow computing, distributed computing, and data mining analysis to construct a load rate early warning model, a pre-installation available capacity early warning model, and a three-phase The unbalance early warning model realizes the data mining of distribution transformer load.

[0033]The specific implementation method is to extract the data in the electricity collection system and marketing business application system through real-time (kafka) or timing (s...

Abstract

The invention relates to an alarm method for an abnormal load of a distribution transformer, and belongs to the field of distribution transformer alarming. According to the invention, periodic fluctuations of the electric power load of the distribution transformer are comprehensively considered through selecting load information data, such as historical load data of the distribution transformer, data of a region to which the distribution transformer belongs, equipment information, customer information data and current and voltage data, of the distribution transformer in a power utilization information acquisition system, a distribution transformer load early warning model is built, and early warning analysis is performed on phenomena such as overloading, excessive loading, heavy loading, underloading and three-phase imbalance so as to solve problems in the prior art that the efficiency is low when mass, fuzzy and messy data is processed, related applications such as big data analysis and mining of the distribution transformer cannot be well supported and the like.

Description

technical field [0001] The invention relates to the field of distribution transformer alarms, in particular to a distribution transformer load abnormality alarm method. Background technique [0002] With the development of all walks of life, the demand for distribution network supply continues to meet urban construction, and the scale is expanding rapidly, and distribution transformation plays a vital role in the process of power transmission. In order to ensure the stability and timely distribution of power distribution It is of great guiding significance to analyze the load data of distribution transformers through advanced computer technology and big data analysis. The current distribution transformer load analysis is based on traditional statistical analysis for data specification, data storage, data calculation and data display. Traditional statistical analysis refers to the use of statistical methods and knowledge related to the analysis object, from quantitative and q...
